Suggested by Karlip to gather more attention for this, so it can be confirmed
Hello, around 3 days ago I've discovered a sync problem. If you're inside a vehicle and have your vehicle's health set to FLOAT_INFINATE, value = " (Float:0x7F800000) " You'll exprience players seeing you fly with nothing but you yourself can see what you're flying [ EXAMPLE IS A HUNTER ], this problem turns out to look like you're airbreaking/fly hacking.
Basicially, players will see you piloting nothing, on your own screen you can actually see what you're piloting.
Just to warn people around about this, don't try it. If you wanna use GOD car or something, you might have to set a >= 750 MS timer for repairing.

When you set the vehicle's health to infinite, other players will see your vehicle exploding while you are
in it or don't see any vehicle, like you said.

Is that possible that vehicle health in SA-MP do not have special values like FLOAT_INFINITE?
If so, then probably it will be recognised as a negative value, which will call OnVehicleDeath.

Hm, I remember I also tried setting the vehicle's health to a big value, like 999999999999999999999999
and the same result came out.

I finally tested it with my friend.
It is the problem of the float size.
I find that when the vehicle health reaches 65536, the others will see the vehicle explode and got desynced (but the vehicle doesn't disappear).
However, the vehicle health is not overflown that you can see them in 32-bit integer by using GetVehicleHealth.
Why I thought a health of 100000 still works is because I can't see the bug on my own.

Now what causes the problem? We could use a developer's answer. Based on one people said SA:MP would return a correct value on GetVehicleHealth, we'd (or I'd) assume GTA:SA is bugged, and it stores the its vehicles' health in a 16-bit float. But I don't think that SA:MP would have an own array which stores all of the vehicles' health which are loaded. Maybe it's just a wild goose chase, but I'd be happy if I could use the standardized infinity values, because I'm used to it.

I guess it could be SA-MP's problem.
If it is GTA:SA's problem, you should also see your vehicle explode, since the vehicle health system in all clients should be the same.
Anyway, it is quite weird, but you have to be used not to use FLOAT_INFINATE in some cases that are related to game data like health, armour, etc..

Vehicle health is a float, not an integer. I can't be bothered to explain the IEEE-754 floating point format, but "0x7F800000" is a special bit pattern for positive infinity. It depends on how the code works internally though, which may be the problem.
